Question

draw a triangle name as yz and another is x. y=40 degree z=60 degree. find the value of x​

Answer 1

Answer:

80degree= x

Step-by-step explanation:

angle y = 40

angle z = 60

angle x + angle y + angle z = 180 ( angle sum property of a triangle )

angle x + 40 + 60 = 180

angle x + 100 = 180

angle x = 180 - 100

angle x = 80 degree.
